Safety and stability for large door elements
When it comes to doors and large door elements, roll-formed steel profiles play a crucial role in ensuring their reliability and durability. Not only do they offer maximum stability, they also provide comprehensive protection against break-ins and external influences.
Strong profiles for strong doors.
For structural reasons, PVC doors require stable steel reinforcements in order to withstand the high stresses of everyday use and at the same time provide reliable burglary protection. We can supply you with ready-to-install profiles that are manufactured exactly to your specifications. State-of-the-art technology such as laser, punching and milling techniques are used to produce precise, durable profiles in various lengths.
- Milled steel reinforcement profiles for front doors
- Steel reinforcements for side entrance doors in special lengths
- Profiles for lift and slide doors for reinforcement or for frames

Entrance doors
Milled steel reinforcement profiles give front doors the strength they need to withstand everyday use and stress with ease. For you as an entrance door manufacturer, we offer numerous steel profiles and work with you to develop the right geometry for your new entrance door system.
- Steel reinforcements for the entrance door sashes
- Steel reinforcement for the entrance door frame
- Reinforcement profiles for the entrance door mullions

Side entrance doors
Side entrance doors connect the indoors with the outdoors – reliably, day after day. They need to withstand heavy use while also providing security, much like main entrance doors. With our steel profiles, you can achieve exactly that:
- Suitable reinforcements for the door leaves of your side entrance doors
- Strengthening elements for the frames
- Profiles that optimally stabilise the posts of the side entrance door
- Special lengths manufactured precisely to your specifications
